When I was in college, I went to a big gun auction. It was well advertised and auction fever was in full effect. Prices were way too high for a poor college kid. It was mostly hunting guns with a few handguns near the end. I walked over to the handgun table and saw a 1911 looking auto that amongst other markings had c 11.25 mm on the slide. Doing some quick math, I figured that had to be very close to .45. Apparently nobody else did that math, or knew what it was and I ended up getting a very nice Ballestor-Molina for $100. I think my budget for the day was around $300, so I felt pretty good! I had that pistol for several years and shot it a good bit before selling it to a buddy who also wanted a .45 but couldn’t affford a ‘real’ 1911!
